PNEUMATIC THREADING DEVICE FOR, SPINNING-MACHINES.

Specification of Letters Patent.

Patented Nov. 26, 1907.

Application riled October 27. 1904. Serial No. 230.248.

To all win-1m it may concern:

Be it known that i, FRANK it. Bmcnzn, a subject'otthe King of .llngland,residing at Philadelphia, in the county of l. hilade|phia and State ofPennsylvania, have invented a new and useful Pneumatic 'lhreading Devicefor Spinning-Machimis, ol which the following is a specification.

My invention relates to a pneumatic device for threading spinningmachines, and it consists in the constructions, combinations andarrangements herein described and claimed.

T he object ofmy invention is to provide a simple ano ellicient meansfor passing the sliver, or other textile material, through the spinningtube and head during the operation of the spinning machine; whereby thesliver can. be mended without stopping the machine.

My invention consists primarily in means for directing, a jet of air, orother suitable fluid, through the spinning tube of a spinning machine,and discharging the et from said spinning tube against the revolvingrollof the spinning head to prevent accidental lapping of the sliveraround said rollers.

in the accompanying drawings, forming a part of this application and. inwhich similar reference numerals indicate corresponding parts in theseveral views: Figure l is a sectional elevation, on the line l t oiFig. 2; illustrating one embodiment of my invention: Fig. 2 is a detailplan view, showing one oi the air nozzles and the adjacent portions oithe air conduit; Fig. I; is a sectional view on the line 3' 3 ol" l ig.'l. and, Fig. -l is a perspective view, showing a portion of a spinningmachine with my invention applied thereto.

l lcterring to the dranings, t indicates a spinning tube and 2 indicatesa spinning head provided with revolving rollers 3; those olcmci' tsheingcommon to existing typos oi machines.

An air conduit -Ll: is shown extending adjacent to the several spinningtn bcs l oi a s inning machine, and provided with a plurality of nozzles5 for dirc-ctii'ig jets of air through the several spinning tubes 1.Each nozzle 5 is shown carried by a valve-plate (5, which is pivotallysecured on a .llattened portion 7 o' the conduit t 1 have shown suchpivotal the conduit t and extending loosely through the valve-plate; allat spring tl, provided with a curved portion 10, being confinedboncath the head oi said screw For insming the proper pressure ol thevalve-plate against its 'llzttt'encd seat.

Each valve-plate 6 is provided with a channel 11 communicating with thebore of the nozzle 5 carried thereby. Each Ilattencd portion 7 oi theconduit 4 is provided with an aperture 1.2 in position to register withthe corresponding channel 11 when the valve-plate is rotated on itspivot S to swing the nozzle 5 into position to discharge into theadjacent spinning tube 1. It will thus be seen that when the nozzle 5has been shifted to discharge into the tube 1, air will be admitted tosaid nozzle through the aperture 12 and channel 1] and that, when thevalveplate 6 has been swung about its pivot 8 to remove the nozzle'l'rom operative position, the channel ll will be swung out of registrywith the aperture 12 and communication between the conduit 4 and nozzle5 thereby cut oil.

If desired, a packing 13 of leather, or other suitable material, may beinterposed between the contiguous faces of the valve-plate G and itsllattoned seat 7, for insuring a satisfactorily tight contactthcrebctwoen.

My invention is adapted to be readily and cheaply attached to manyexisting typos ol spinning machines, and it provides a very oilicicntand convenient means for introducing a sliver, or other textilematerial, to said machine while in opm'ation.

laving thus described my invention, what I claim as new and desire tosecure by 11Gb tors Paton t is:

l. The combination with a spinning ma chine providcd with a series ofspinning tubes, of a common air conduit, a series of independent nozzlcsmou ted on said conduit, each ol" said nozzlcs being mounted l orindopondcot rotation to operative position for directing a jet ol airfrom said common con.- duit through the adjacent spinning tube, andspring mcans for maintaining said nozzles in closed position,substantially" as described 2. The combination with a spinninginasupport comprising a screw 8 threaded into chine provided With aspinning tube, a spinning head, and rollers carried by said head, of anair conduit, a nozzle rotatably supported on said conduit for directinga jet of air through said tube, and a spring plate for in suring a closecontact between said tube and conduit, substantially as described.

In Witness whereof I have hereunto set my hand in the presence of twoWitnesses.
